My first robot! Before buying, I chose for two years according to different parameters . As a result, I took my order, bought it, a month ago! There are three cats and a dog in the house. I used to run with a corded vacuum cleaner and a mop, and now my favorite assistant is running! I installed the application, the smart guy himself runs around the rooms twice a day. The house is clean and tidy! Why didn't I buy earlier.
